The radios in the pictures and Ricochet were originally
made by the same company, Metricom. This company was started by Southern
California Edison. Metricon made both radio systems, that
were the Ricochet and the Utilinet radios systems. They
sold off the utilinet radios and that radio system has been sold several
times, now made by a company called Cellnet. Metricom company kept
the Ricochet system and installed the system in several cities around the
US. Than Metricom went bankrupt and the Ricochet system was sold
to a company in Denver, but they never had much luck selling the
systems to end users (only 19.2Kbs)....

Utilinet radios are used all over the place. The
odd thing about the pictured radio is that it is an old metricom radio that
hasn't been manufactured for about 12 years.....
